Optical Coherence Tomography
Since 1996, McPherson Optometry has used digital technology to photograph the back of the eye to enable a more comprehensive examination and detection of abnormal eye conditions. Optical Coherence Tomography (OCT) takes this examination a step further by taking a CT scan of the retina. This technique gives a series of cross section images of the retina and is particularly useful to diagnose Age Related Macular Degeneration (AMD).
It is also used to differentiate between the wet and dry types of this condition to decide whether treatment may be possible. Many other eye conditions can also be diagnosed with this equipment and of course it can also confirm that all is well and the eye is healthy. The test is easy to conduct and the scan only takes a few seconds to complete. Usually the pupils require to be dilated to ensure clear images are obtained.
